`3 Claims.

This invention rela-tes to improvements in Window ventilators of the type which is adapted to be secured within the window -frame in a position that it will not interfere with the opening or closing of the Window, and one of the objects of the invention is to improve and simplify the construction of such ventilator and at the same time provide a simple, effective and inexpensive device of this character.

A further object is to provide in an improved ventilator of this character improved means for securing the same in position whereby it may be readily removed and as readily replaced.

A further object is to provide an improved adjustable ventilator of -this character which is also of a knock-down or collapsible construction for shipment and storage purposes.

A further object is to provide van improved combined ventilator and screen which latter may be readily removed and as readily placed in position Without interfering with or removing the ventilator from the window.

AA still further object is to provide an improved screen attachment for a ventilator of this character and whichscreen is readily .adjustable tot Windows of various-sizes.

To the attainment-of these ends and the accomplishment of other new and useful objects as will appear, the invention consists in the features of novelty in substantially the construction, combination and :arrangement of the several parts hereinafter more fully described and claimed and shown in the .accompanying drawing illustrating this invention, and in which Figure 1 is a perspective view ofa ventilator of this character, constructed in accordance with the principles of this -invention and showing the same as applied-to a window frame.

Figure 2 is an elevation on an enlarged scale, of one of the end members before the body member or screen are secured thereto.

Figure 3 is a detail sectional view, on an en larged scale, as taken on line 3 3, Figure 1.

Figure 4 is a detail sectional view taken on line 4 4, Figure 1.

Figure 5 is a detail perspective view, on an enlarged scale, of one of the end members.

Figure 6 is a detail sectional view on an enlarged scale, taken on line 6 6, vFigure v1.

Figure 7 is an enlarged detail sectional view taken on line 1 1, Figure 4, With parts omitted.

The ventilator consists essentially vof end members I0 of any desired size 4andconiigurationfbut are preferably substantially triangular, the'upper .end II being of `a greater length than lthe lower end I2.

These end members may be constructed of any suitable material but are preferably formed 'of metal of a comparatively thin gauge, and in order to impart rigidity thereto there may be provided a'peripheral reinforcing flange I3.'

'The front edge I4 of each of the end members is ypreferably "inclined to the vertical and there'fis provided a laterally'projecting seam I5 formed by bending a portion of the edge back upon itself lto provide a channel or groove I6 `that extends for substantially the length -of the edge rI4 but terminates a short distance from the flange lf3.

A portion of the seam I5 may be shaped yto provide a lip or projection I'I which initially projects below the lower vedge I2 of the end, member.

Two of these end members are -provided and each is also provided with akeyhole slot |18 in its body, suitably located.

The body of the ventilator 'is for-med of two members I9 2D also constructed of any suitable material but preferably metal arranged in-foverlapping relation; v'The upper edge `of oneef the members, such as the member v2llmay be shaped ltoy provide a tubular formation 2|, the kedge-of vsuch formation being spaced from the fbodyfp'or tion v26 to form an'opening 22.

The upper ledge of ythe body member v|19 vmay yalso be shaped to-provide a tubular portion 23 Awhich telescopes-into the tubular portion 2 I, and fa portion of the body member I9 passes through the opening 22 so that these two 4members'willoe "adapted for free longitudinal relative adjustment.

The lower `edge of 'the body members :I'9 2;0 may bev shaped to form Ichannels 2-4 25V one 'of which ts within the other :for sliding relation, 'and serves to prevent lateral separation ofthe body members Ill-20 at the lower edge thereof.

The lfree extremity `of each of the body members lll-2B is bent back upon itself as at` 26and this portion 26 is adapted to telescope into the groove lr6 of the seaml I5 of the adjacent 2end member I0 therebyforming a telescoping or ad-` justable seam connection between the respective end members and the proximateend of the adjacent body member. l

'With this construction' it will be manifest Athat Athe end membersmay be detachably connectedto the bodymembers,so that they may be separated therefrom and the ventilator `may be collapsed .or knocked down, and may a-sreadily be assembled.

`In order toA prevent separationor detachment of the end members ffrom the respectivefbody members, the projection or vextension Il-,.ongthe end members may be provided, and this projection is adapted to be anged or bent over the lower edge of the respective body member, as shown more clearly in Figure 3 of the drawing.

The .projection I'I co-operates with the reinforcing rib or flange I3 to lock the parts together as the extremity of the tubular formation at the upper edge of the respective body members I9--20 will pass under the flange I3, as shown more clearly in Figs. 3 and 6, and will hold the body member against being raised with respect to the endv member while the lip or projection I'I will hold the body member against being lowered with respect to the end member.

Furthermore, the extremities of the body members I9`20 ,passing under the respective adjacent flanges I3 will be concealed and the space be-` tween the body member and the end vmember will be closed by the ange I3.

When, however, it is desired to `detach the' end vmember from the body member, this projection 'I 1, if employed, may be bent back into its normal position or out of the Way so as to permit such detachment. Y

When the parts are thus assembled the ventilator may be secured in position and to a window frame by means of a headed screw or bolt 21 which passes through the keyhole slot I8,

thereby providingV a means which will permit of` vready, detachment of the ventilator from the window frame.

Two of .the fastening velements 2'I are all that are necessary as the keyhole slots I8 are so positioned in the end members that when the head of the screw is passed through the enlarged por` tion of the'slot, the end members and ventilator may be dropped down until the bottom I2 of the end member rests upon the window sill. This willi `maintain the ventilator from swinging about the fastening devices 2I. ,Y

shaped to form a laterally projecting flange 32 l,

and secured to the face of each of the members zas-29 adjacent and withinV the respective flanges is a member 33. The member 33 .terminates short of the adjacent flange 32 and a space 34 is formed between the members 33 a 'andtherespective screen-members 28-29. An upright flange 35` is provided along the rear i edge` of the respective end member I and this ange terminates short of the flange I3 to form a space 36 at the upper rear corner of each end member I0, l f

Thisv space is provided to permit the screen to be placed in position by inserting the flange 35 in therespective spaces 34 between the member 33 and `the screen member from the lower edge of the screen members.

close proximity to the window but it will not interfere with raising or lowering the window.

Furthermore as the screen is secured to the end members and is adjustable in a manner similarA to the body members I 9--20 of the ventilator the size of the ventilator and screen may be varied by adjusting the end members I0 laterally with respect to each other.

With this improved construction it will be manifest that the ventilator is not only adapted to be readily detached from the window frame without the adjustment of any screws or fastening devices but at the same time is adapted for adjustment to t windows of varying widths.
